PLOW-CLEVIS.

SPECIFICATION forming part'of Letters Patent No. 278,453, dated May 29, 1883, W

Application filed July 24, 1882. Renewed April 19, 1883. (No model.)

To all whomit may concern:

Be it. known that I, ANDRnwPA'rroN, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Plow-Olevis, of which the following is a full, clear, andexact description.

My invention consists of improvements in the device for hitching the team to'the clevis,

, field or when in use, all as hereinafter fully de having-for its object to prevent the hitching, 'device from dropping out of the notch in the clevis-head by which the pitch of the draft of the plow is regulated, andl propose to rivet the ends of the clevis-bolts over the washers or nuts, for guarding more effectually against their loss by theft orotherwise when left in the scribed.

Reference is to be had to the accompanying f drawings, forming apart of this specification,

in which similar letters of referenceindicate corresponding parts in both the figures. I

Figural is a. perspective'view of a plowclevis with my improvements, and Fig. 2 is a perspective view of a modified form of part of the hitching device.

I propose to use either a hook, at, or an eye,

I), and a small clevis, c, for hitching the team to the notched head of the main clevis d, connecting said hook or eye to clevis c by a bolt, e, and I make the said hook or eye with a grooved and inclined butt extension, f, sufficiently long to bear on the head d and prevent the hook pr eye and clevis c from swinging downward and falling out of the notch g, in which the device may be set, so that when once setin position the device will not fall down a and require resetting, as such devices now do, causingrnnch trouble and delay. The inclined and I propose to rivet bolts 0 and h overtheir nuts 1', tomprevent them from being stolen out;

or the bolts 0 h, or either of them, may not be so riveted over, if desired.

With this constructionthe clevis ofthe hook or eye is held engaged in a slot 9 by the weight of the parts, and by swinging the outer end of the hook or eye upward the clevis may be almost instantly disengaged and as quickly readjusted in any one of the slots g, to regulate the working depth of the readily understood. it

Having thus described myinvention,Iclaim as new and desire to secure byLetters Paten t- 1.An improved clevis attachment consistplow,:as will be ing ofa hook or eye having an inclined and grooved extension to fit upon the head of any ordinary clevis, and a small clevis pivoted to said hook or eye and adapted to engage with the notches of saidordinary clevis, substantially as herein shownand described.

2. The combination, with the notched clevishead 0?, ofthe hook a, having theinclined and grooved extension f, and the small clevis c, pivoted to said hook and engaging withthe notches of the said clevis-head, substantially as and for the purpose set forth.
